Answer:

D. 39

you use the pythagorean theorem which is
a^(2)+b^(2) = c^(2)

if you look at the triangle we can see that we have to find the length of the hypotenuse (BC).

so your equation will look like this:

15^(2) + 36^(2) =c^(2)

1.
15^(2) + 36^(2) =c^(2). (solve for
15^(2) and 36 ^(2) )

2. C= 225+1296 (add)

3. C= 1521 (find the square root of 1521)

4.
√(1521) = 39

Therefore, 39 is your answer

Hope this helps!
